Post Mortem Changes

What post-mortem change in fish results in the stiffening of muscles after death?

• Autolysis

• Lipid oxidation

• Rigor mortis

• Proteolysis

What is the characteristic compound responsible for the fishy odor associated with fish spoilage?

• Ammonia

• Hydrogen sulfide

• Lactic acid

• Trimethylamine (TMA)

Algor mortis is characterized by what post-mortem change?

• Cooling of body after death

• Stiffening of skeletal muscles after death

• Pooling of blood in tissues after death

• The heat generated by a body after death

This occurs 2-8 hours after death, where the blood pools due to gravity. The area affected is a purplish-red color.

• rigor mortis

• algor mortis

• livor mortis

An elderly man is found dead in his car with the windows down. He has been missing for 2 days. The average temperature has been 36 degrees F. How would these factors affect lividity, rigor mortis, and algor mortis rates?

• lividity - decreases

  rigor - decreases

  algor - increases

• lividity - decreases

  rigor - increases

  algor - unaffected

• lividity - decreases

  rigor - unaffected

  algor - increases

• lividity - increases

  rigor - increases

  algor - increases

The process that causes the muscles in the body to stiffen resulting in rigidity after death is called

• algor mortis

• rigor mortis

• livor mortis

How long does lividity last?

• 2 weeks

• forever

• 24hrs

• 36hrs

the stiffening of the skeletal muscles shortly after death

• livor mortis

• autolysis

• rigor mortis

• algor mortis

The cooling of body temperature after death is:

• algor mortis

• livor mortis

• rigor mortis

• pallor mortis

A cold environment causes algor mortis to occur

• faster

• slower
